DrawCamera

DrawCamera CameraIndex

Parameters:     CameraIndex = The Index Identifier of the Camera that you wish to create.

Returns: NONE

DrawCamera will render what is in view of a camera (what's in front of it) to it's attached surface. What is drawn is determined by the position of the graphics elements that were captured to the scene buffer.       For more information about cameras pease read the CameraBasics tutorial in the About Section. FACTS:       * DrawCamera will automatically Sort and draw the items in the Scene buffer, so those items with the lowest depth will be drawn in front of items with a higher depth.       * Cameras by default have CameraCLS backdrop enabled.       * See CameraSceneSort to stop the camera from sorting the scene items.
